IndyCar and NASCAR will both race this weekend without spectators over fears of the COVID-19 pandemic. IndyCar is scheduled to open its season Sunday on the streets of St. Petersburg, Florida. Only essential personnel will be permitted to attend. Competitors will also undergo a questionnaire for health screening before entry. NASCAR will race this week at Atlanta and next week at Homestead-Miami Speedway under similar restrictions. The NHRA has canceled much of the GatorNationals and IMSA rescheduled the 12 Hours of Sebring in Florida. 554

It may have been a rabbit puppet that stole last night's Academy Awards show.There were several funny moments at the Oscars, and one certainly stood out: Comedian Melissa McCarthy's over-the-top Queen Anne costume included a rabbit puppet that "spoke" as she and Brian Tyree Henry spoofed "The Favourite" while presenting a costume design award.Henry's 1700s costume also helped deliver the laughs.Watch the moment and a few others that made the Oscars a fun time: 508

Laurie Sylvia, the fourth person in Massachusetts infected with Eastern equine encephalitis (EEE) since the beginning of August, has died.Sylvia was being treated at Tufts Medical Center in Boston after contracting the dangerous mosquito-borne virus that causes brain swelling in humans, said Jeremy Lechan, Tufts' senior media relations specialist.The other cases of infection this month are those of two men over 60 and another man between 19 and 30.This is the first time EEE cases have been reported in Massachusetts since 2013.State epidemiologist Catherine Brown told CNN in a statement that warmer temperatures and above-average rainfall in July sped up virus replication in mosquitoes, which could explain the uptick in EEE activity.Migratory birds might have even spread a new strain of the virus, though lab tests that could prove that have yet to be completed, she said.In Florida and Delaware, the virus has been detected in sentinel chickens, though neither state has seen any cases reported in humans.EEE kills one-third of those infectedEEE is rare but potentially fatal. Anywhere from 5 to 10 human cases are reported every year, but about 30% of all cases are fatal, according to the 1213

LAKEWOOD, Colo. – Police have cited five people for a fight that broke out during a youth baseball game this past Saturday that seriously injured one person.Lakewood police tweeted the video Tuesday, showing several adults taking over the baseball field at West Gate Park and assaulting each other. The Bear Creek Junior Sports Association announced on Wednesday that it had canceled the season for the two teams involved and that coaches and parents who participated in the brawl would be removed indefinitely.These adults took over the field and began assaulting each other on 6/15 during a youth baseball game. We're looking for any info, in particular to ID the man in the white shirt/teal shorts. Several people have already been cited in this fight and injuries were reported. 800

In regions of the United States and Mexico that are prone to hurricanes, aggressive spiders are evolving to survive and ride out the storm.When hurricanes rage along the Gulf of Mexico or charge up the East Coast, they can reshape an entire habitat in a short time. The winds destroy trees and spread debris for miles, putting new pressure on the creatures living in these environments.But how do creatures adapt when their habitats are so disturbed? Researchers looked at Anelosimus studiosus spiders that live in storm-prone areas along the coast to see how they changed. Their study was published Monday in the journal Nature Ecology and Evolution.These weather systems are called "black swan events": a surprising event with a major impact that is explained with the benefit of hindsight. They don't offer much lead time, so the researchers had to scramble to study the spider colonies before and after projected storms.The team monitored Subtropical Storm Alberto and Hurricanes Florence and Michael during the 2018 hurricane season. They tried to anticipate the systems' trajectories and study areas that included 240 female spider colonies, comparing them with areas where spider colonies were unaffected by such storms.The researchers returned to the sites hit by the storms 48 hours later. About 75% of the colonies survived the initial storm strikes."It is tremendously important to understand the environmental impacts of these 'black swan' weather events on evolution and natural selection," said Jonathan Pruitt, lead study author, evolutionary biologist and Canada 150 Chair in McMaster University's Department of Psychology, Neuroscience & Behaviour. "As sea levels rise, the incidence of tropical storms will only increase. Now more than ever we need to contend with what the ecological and evolutionary impacts of these storms will be for non-human animals."The A. studiosis spider species has two main personality traits that are inherited: docile and aggressive.Aggressiveness can be determined based on their speed, attackers pursuing prey, cannibalizing male spiders as well as eggs and their vulnerability to the invasion of predatory spiders.On the one hand, aggressive colonies are better at gathering resources in times of scarcity. But when deprived of food or subjected to overheating, aggressive colonies can also suffer from infighting."Tropical cyclones likely impact both of these stressors by altering the numbers of flying prey and increasing sun exposure from a more open canopy layer," Pruitt said. "Aggressiveness is passed down through generations in these colonies, from parent to daughter, and is a major factor in their survival and ability to reproduce."The researchers determined that after a storm passed, the colonies that aggressively pursued food and resources were able to produce more egg cases. The spiderlings also had a better chance of surviving into early winter.In areas that weren't hit by storms, docile colonies thrived.These findings were consistent even as the storms varied in duration, intensity and size. The researchers believe this shows that extreme events can shape animal behaviors. They would like to conduct more long-term studies to learn whether this is the case. 3250
